MANUFACTURE AND COLORING OF RUBBER TOYS, 8.0.

SPECIFICATION formingpart of Letters Patent No. 247,838. dated October 4, 1881.

' Application filed May 7,188]. (No specimens.)

Toall whom it may concern:

Be it known that I, THOMAS J. MAYALL, of Reading, in the countyot' Middlesex and'Oommonwealth of Massachusetts, have invented a new and useful Improvement in the Manufacture and Coloringof Rubber Toys for Children and other Objects, of which the following is a specification.

Heretofore the coloring of toys for children made of rubber ha-sheen put on with paints after the rubber has beencured or vulcanized, and consequentlyit is liable to and does come 05 by use, and in the hands of young children is often very deleterious to health and dangerone tolife.

' The objectot' myinvention is to incorporate the colors desired in'toys and other objects.

made of rubber in the rubber before it is cured,

so that after the rubber is cured'the color will not come off; and it consists inv mixing and thoroughly.iutermingling rubber and colored sulphide or sulphuret of antimony of the color or. colors required, dissolving the compound in.

. naphtha or other suitable solvent of rubber to a thin fluid solution, painting the color or colors desired-on the toy or other object ot'rnbher after it has been molded into its required shape and form, and then curing the toy or other object and the colors painted onto it together in any suitable way or manner of cur-.

ing nubber by heat.

By means of recent improvements in (heart- 7 of reducing natural ores of antimo'nyto sulphides o'rsulphurets oi antimony the sulphides 5 or sulphurets are produced of all colors and shades of colors. Linake paints forcoloring toys and other objects made of rubber by mixing pure rubber with each and all the various colored sulphides or sulphurets of antimony,

. 40 and dissolving the compound in naphtha or other solvent of rubber and reducing the sol 11- tion to the proper degree of fluidity to be conveniently. manipulated and applied with a brush, as artists ordinarily apply paints with a brush to canvas. Y Y

Having paints made in the way described of all the various colors at hand, a person skilled in theart of painting will apply them to toys and otherobjects, afterthey are formed or molded and before they are cured or vulcanized, using such colors and combination of colors and designs as will give the desired ornamental or other appearance to the. toy or object. The toyor object is then cured or vulby heat in any suitable manner.

canized, either pliable and soft or as hard rubber.- The colors thus applied and fixed are then permanent, and eanno't'be rubbed or washed off, being in and a part of the toy and insoluble in any solvent.

I also apply desired colors to rubber toys and other articles by running the compounds of rubber and sulphide or snlphuret of antimony inall the various colors out into very thin sheets; From these thin sheets I cut out patches of anyoutline of form desired. These patches are.- affixed to the surfaceof the toy or other object after it is formed and before it is cured by the use of the tluid' paint compound described, and then the whole is cured togethei Thus por traits, landscapes, and pictures of any and al designs may be painted on rubber toys or othei objects, or on rubber in any forin ready forcur ing,with therubber and sulphide of antimony paints described, and made permanent in tlu rubber by the curing process.

I claim as newand my invention- 1. The above-described improvement in thi art of coloring and ornamenting rubber toy: and other objects, consisting of paiutin g the sur face of the toy or other object when itjs ready for curing with paints, made of compounds 0 rubber and colored sulphides or sulphurets o antimony dissolved, and then curing-the whoh together, substantially as described.

2. As a new article of manufacture, rubbe: toys and other objects painted and cured sub stantially as described.

3. As a new article of manufacture, rubbe objects in any shape or form having portraits landscapes, or any other pictures'paiuted wit] paints made of rubber and sulphides of anti mony dissolved together on the rubber, \vhei it is formed readyfor curing, and then ClllGl by heat, substantially as described.

' 4. Theabove-described method of coloring or ornamentin g rubber toys and other articles consisting of making very thin sheets of ruh her and colored sulphides or snlphurets of an timon y, cutting patches from the colored sheet. and aflixin g them to the surfaceot' the toy 0 other object before it is cured, andcuring th whole together, substantially as described.
